The second approach to mitigate JIT overhead is to cache the binaries generated by JIT compilation. When the device driver just-in-time compiles PTX code for an application, it automatically caches a copy of the generated binary code to avoid repeating the compilation in later invocations of the application. … See more The first approach is to completely avoid the JIT cost by including binary code for one or more architectures in the application binary along with PTX code. The CUDA run time … See more It is helpful to know the above options so you can recognize and avoid problems. Let’s look at two example situations: insufficient JIT cache size and cache stored on a slow network share. See more For more information on the CUDA compilation flow, fat binaries, architecture and PTX versions, and JIT caching, see the CUDA programming guide section on “Compilation with NVCC” and the NVCC documentation. See more WebFeb 27, 2024 · The CUDA driver will cache the cubins generated as a result of the PTX JIT, so this is mostly a one-time cost for a given user, but it is time best avoided whenever possible. PTX JIT-compiled kernels often cannot take advantage of architectural features of newer GPUs, meaning that native-compiled code may be faster or of greater accuracy. …

According to the opencv documentation, it could be doing the JIT PTX compilation, and that CUDA_DEVCODE_CACHE should be used to cache the PTX code for future use, but that feature does not seem to be working.
